" inwardly from the top to the bottom and grooves along `the overhanging edges, the

upper ends of the spaces between'the bars of the movable grid being'narrower than the width of the bars of the stationary. grid, andthe lower. ends of'said spaces being wider than the bars of the stationary-grid, whereby when the grate is closed'the'npper edges of the bars of the-movable gridwill overhang the bars of the stationary grid, and the lower edges of the bars of 'said mov` able grid vwill be lspaced from the upper edges of the bars of the stationary grid.'

2. A grate comprising a stationary grid 'formed with spaced bars, and a movable grid superposed on the stationary grid andy formed with spaced bars having their edges beveled inwardly from the top tot-he bottom, the upper ends ofthe beveledsaces between the bars of the movable grid ,eilig narrower than the width of thefbars of the stationary grid' and the lower ends of said beveled spaces being wider than the width ofthe bars of the stationary grid, and thev upper faces of the bars of the movable grid being wider than the spaces between the bars of the movable grid whereby when the grate is. closed air passages will be :formedl between thelower'edges of the bars-or the, movable grid and the upper edges of the bars ofthe stationary grid, and the edges of the bars' of the movable grid will overhang the `bars of the stationary grid.

3. A. grate comprising a stationary grid formed with spaced bars provided withde.

Vpressions for the reception or' ashes, anda movable grid superposed on the l,stationary grid and formed with spaced cross-bars provided with depressions to receive ashes and having sides inclined inwardly from top to bottom, the upper ends of thespaces between the bars of the movable grid being narrower than the width ofthe bars of the movable grid, the lower ends of said spaces being wideruthan the width of the bars of the stationary grid, whereby when the grate is closed the upper vedges of the bars or' the inovablegrid will overhang the bars of the 'stationary grid, and the upper edges 'of the .bars of the stationary grid will be spaced from the lower edges of the bars of the movable grid.. i

4. A grate comprising a stationary grid formed with spaced cross-bars provided on top witlrdepressions, and a movable lgrid superposed Aon the stationary grid and formed with spaced cross-bars having their edges beveled inwardly from the top to the bottom and their bottomslat, the flat bot- 'toms of the bars of the movable grid being on a plane'with the upper! edges of the bars of the movable grid adjacent the depressions therein, the lripper ends of the spaces lbetween the bars of the movable 'gri-d being narrower- I able grid.

ing wider than the width of the barsefl the stationary grid, whereby whenthe grate is closed the upper edges of the bars of the movable grid vwill overhang the bars of the stationary grid, and the upper edges of the bars of saidstationarygrid will be spaced from the lower vedges o1" the bars of the mov- 5. A grate comprising amovable grid vformed with spaced cross-bars' with their sides inclined downwardly and inwardly I and having grooves in the sides and de# pressions in their upper surfaces to receive ashes, a stationary grid having spaced crossf bars with depressions to receive ashes, the

movable grid being superposed on the stationary grid, the upper edges of the bars of the movable grid overhanging the bars of closed spaceswill be formed-between the lthe stationary grid when the grate Ais in lower edges of the. bars of the movable grid i and the edgesof the bars of the stationary.

grid. A gratecomprising a movable, grid having spaced cross-bars j with their sides inclined' downwardly vand inwardly and. formed with grooves in their side edges, and

a stationary 4grid formed with spaced crossbars, tlielmovabl-e grid being snperposed on the stationary grid, the upper edgeso the bars or" the movable grid overhangingthe bars of' the stationary grid when'the grate is in closed position and the lower ends of the spaces of the movable grid being wider than to receive ashes and having vsides inclined.v

inwardly rom the top downwardly, asta- `tioiiary grid having cross-bars, the movable grid. being snperposed on the stationary grid, theA ripper edges of the bars of the movable grid overhanging the bars .or the stationary grid whenthe grate is' in'v closed position and the spaces 'at the top of the movable grid between the cross-bars thereof being narrower than at the'bottom of Said bars, and the bars of the stationary grid being narrower than the lower ends 'of the spaces of the movable grid, wherrbyr when 'the grate is closed the top' edges of the bars of the stationary grid will be spacedv from the'lower edges of .the bottoms of the bars of vthe movable grid,v

` .8.; grate comprising a grid having 105 t ie width of the bars of the stationary grid,

eeepee spaced cross-bars, a second grid having spaced cross-bars, one stationary and the other being reciprocatingly mounted thereon, the bottom of the spaces between the bars of the second mentioned grid being Wider than the upper edge of the cross-bars of the first-mentioned grid, the upper edges of the bars of the-upper grid overhanging the bars of the stationary grid when the grate is in closed position `and the lower edges of the bars of the movable grid spaced from the bars of the stationary grid whereby when the grate is closed air passages are formed each side the bars of the first nientioned grid, the upper faces of both grids being formed with depressions.

9. A grate comprising two grids one superimposed upon and movable with relation to the other, each grid being formed of spaced bars, those of the movable grid I having inwardly inclined sides with theirfupper edges overhanging the bars of the stationary vgrid when the rate is in closed position, the lower edges cfg the bars of the movable grid being spaced from the bars of the stationary grid whereby when the grate is closed passages are provided for the air adjacent the inclined sides vof the upper grid. In testimony whereof I aliix my signature, in presence of two subscribing Witnesses.
